3,099,017 DISPGSABLE, C(lLLAPSiELE URENAL Lawrence J. faullivan, LosAngeles, Calif. (526% Palm Drive, La Canada, Calif.) Filed May 31, 1962,Set. No. 201L693 12 Claims. (Cl. 4-1113) This invention relates to adisposable, collapsible urinal.

This application is a continuation-in-part of applicants co-pendingapplication, Serial No. 109,126, filed May 10, 1961, entitledDisposable, Collapsible Urinal.

There is need in hospital operations, particularly in evacuationoperations and the like, for a urinal which can be stored in a smallspace, set up conveniently, and after usage be easily disposed of. Inaddition, such a disposable urinal should be lightweight, leakproof, andhave enough rigidity to remain folded or set up as desired.

In addition, as the cost of hospital help has gone up, and its supplyhas gone down, the requirement has arisen for a low cost urinal whichcan be issued to an individual, which can be used for about a week withonly rinsing between uses, and which is cheap enough to be thrown away.This saves the cost, nuisance, and noise of sterilizing urinals.

A urinal according to this invention meets the above requirements andovercomes the objectionable features of some of these urinals which havebeen known in the prior For example, many of the known devices require aseparate bottom and sidewall piece which must be sealed together, oftenalong curved edges. This gives rise to difficult sealing and leakageproblems. It is an object of this invention to provide a urinal whichcan be folded up from a single flat piece of material which ispreferably scored for convenience in folding, and which can be made outof a single piece that encompasses the top, sides, bottom and open neck,and which eliminates most of the difficult sealing problems, requiringonly sealing of straight edges and flat surfaces.

A feature of the invention resides in scorings which permit the deviceto be folded up to its erected or collapsed configurations.

A preferred but optional feature of this invention resides in theprovision of a folded handle structure which acts to hold the urinal inits erected configuration.

The above and other features of this invention will be fully understoodfrom the following detailed description and the accompanying drawings inwhich:

FIG. 1 is a side elevation of a urinal according to the invention shownin its setup configuration;

FIG. 2 is a plan view of the blank from which the device of FIG. 1 isformed;

FIG. 3 is a top view showing the device in its partially folded upconfiguration;

FIG. 4 is a top view of the device in one of its collapsedconfigurations;

FIG. 5 is an edge view of FlG.

FIG. 6 is an edge view of another collapsed configuration;

FIG. 7 is a plan view of a blank for forming the presently preferredembodiment of the invention;

FIG. 8 is a side view of the erected configuration of the blank of FIG.7; and

FIG. 9 is a top View of FIG. 8.

In FIG. 2, there is shown a blank from which the device of FIG. 1 isformed up. This blank is a single sheet of foldable fluid-impermeablematerial, preferably fairly st-iif stock. However, for devices intendedto be flushed away after only a single use or two, the material may besomewhat more flexible, still being stiif enough that it will notreadily collapse in use.

Waxed or plastic-coated paper stock of adequate weight, strength, andthickness is suitable for devices intended iittl rates l stens it 3 1 7Patented July 30, 1963 for reuse. For very lightweight urinals intendedto be used only once or twice and then thrown away, fairly heavy gradesof parchment are adequate.

For convenience in forming up the device, scores are provided in thesurface of the blank and these are indicated by dashed lines. Thesescores direct the folds. The relative spatial locations of the edgesformed by these folds uniquely determine the shape of the erecteddevice. They are located so as to form a stable structure.

The blank includes a neck edge 11, a bottom edge 12, and two side edges13, 14.

A bottom surface 15 is defined by 43. bottom front score 16, a closurescore 17, and a pair of bottom side scores 18, 19. The bottom surface isgenerally trapezoidal, scores 16 and '17 being parallel, and scores 18and 19 converging toward each other as they approach the bottom frontscore.

The device is symmetrical around a center line 21 so that theconfigurations recited for the surfaces on one side thereof will be thesame as those on the other.

Contiguous to the bottom side scores are two pairs of body flutesurfaces 21, 22, 23' and 24, body flute surfaces 21 and 23 beingcontiguous to and partially bounded by bottom side scores 13 and 19,respectively.

Body flute surfaces 21 and 23' are further bounded by closure scores 25,26 and by body flute scores 27, 28, re spectively. Body flute surfaces22 and 24 are bounded by closure scores 29, 30 and by body side scores31, 32, respectively, as well as by body flute scores 27 and 28,respectively. Body flute surfaces 21-24 are substantially isoscelestriangles, and are nearly congruent.

Bottom side score 18, body flute score 27, and body side score 31 meetat a body iiute base junction 33, and scores 19, 23 and 32 meet at abody flute base junction 34. These junctions are not precisely points,and are indicated by dotted lines as regions. However, scores 27 and 18and scores 19 and 255 do meet at a single point within the regions.These regions do act as junctions, but each includes two points ofintersections, to minimize the amount of folding taking place within alimited area. It is desirable, but not essential, to limit the number offolds adjacent to a single point. However, *as to function of thesurfaces which converge at these junctions, their result is still thatthe junctions function substantially as points in determining the shapeand configuration of adjacent areas.

Closure scores 17 and 25 meet at a base junction 35 with bottom sidescore 18. Closure scores 17 and 26 meet at a base junction 36 withbottom side score 19.

Two side surfaces 37, 38' are contiguous to body flute surfaces 22 and24-. Surfaces 37 and 38 are bounded by body side scores 31, 32, body topscores 39, 40 and side transition scores 41, 42, respectively. The sidetransition scores are essentially continuations of the bottom frontscore and emanate from the respective body flute base junctions 33 and34 to front junctions 43', 44, respectively. The body top scoresinterconnect respective front junctions with side junctions 45, 46 atwhich meet closure score 29, body side score 31 and body top score 39 atjunction 45, and closure score 39, body side score 32 and body top score40 at junction 46.

A neck bottom surface 47 is contiguous to bottom surface 15 and isbounded at one side by bottom front score 16. A pair of neck side scores48', 49 extend forwardly away from the bottom surface and intersect theneck edge. The neck side scores include neck medial junctions St 51 atwhich the neck scores deviate a bit to form an obtuse angle to aid informing the device. The neck side scores are not, strictly speaking,straight lines because of this deviation, but the segments are. Betweenmedial junctions 59, 51, there extends a theoretical neck medial line 52which may be scored to form a E3 neck medial score 53 if desired.However, this neck medial score is optional as will later be described.

Two first neck flute surfaces 54, 55 are formed contiguous to the neckbottom surface and are bounded partly by neck side scores 43 and 49,respectively. They are also bounded by neck flute scores 56, 57 and bythe neck edge. The flute scores intersect at the region defined as bodyflute base junctions 33 and 34, although they are somewhat spaced apartfrom the neck side scores to avoid excessive folding stressconcentrations at a single point as hereinabove described.

Second neck flute surfaces 58, 59are formed contiguous to respectivefirst neck flute surfaces and are bounded by one side by neck flutescores 56 and 57. They are further bounded by neck top scores 61 61 andby side medial scores 62, 63, respectively, and also by the neck edge sothat they are essentially quadrilateral surfaces. The neck top sourcesare spaced from and do not intersect with their respective neck flutescores, and make intersection with respective front transition junctions64, 65, which front transition junctions are spaced apart on the bodytop scores from the respective front junctions.

A pair of neck body transition scores 66, 67 interconnect front junction43 and neck medial junction 50 and front junction 44 and neck medialjunction 51, respectively. Neck transition surface 68 is bounded by neckbody transition score 66, side medial score 62, and that portion of bodytop score 89 which lies between front junction 43 and front transitionjunction 64. Neck transition surface 69 is bounded by neck bodytransition score 67, front transition score 63, and that portion of thebody top score 49 which lies between front junction 44 and fronttransition junction 65.

Bottom transition surfaces 92, 93 are bounded by neck body transitionscores 66, 67, side transition scores 41, 42, and those portions of neckside scores 48 and 49 which lie between the neck medial junctions andthe body flute base junctions, all respectively.

Neck top surfaces 70, 71 lie contiguous to second neck flute surfaces58, 59, respectively. They are bounded at one side by neck top scores6%) and 61, respectively, at their other side by side edges 13 and 14,respectively, and by the neck edge. Theoretical top medial lines 72, 73extend from front transition junction 64, 65, respectively, toward theside edge. Their precise location will be discussed more fully below. Atop medial score 74, 75 may be impressed along these lines but isoptional as will also be further discussed below. This medial linedefines the lower extent of the neck top surface.

Body top surfaces 76, 77 are contiguous to side surfaces 37 and 38,respectively, and are bounded by them, by closure scores 78, 79,respectively, by the medial lines 72 and 73, respectively, and by theside edges.

The upper edge, preferably but not necessarily, has three rounding tabs80, 8'1, 82. Tab 8 1 lies between neck flute scores 56 and 57, whilerounding tabs 81 and 82 lie on opposite sides thereof. Locking tabs 83,84 lie on opposite sides of the three rounding tabs. All of the tabscould be deleted and the device could be cut off to form an edge at tabscore 85' if preferred, but as can be seen from FIG. 1, the roundingtabs fold down to provide a nice rounded edge which will not cut, and atleast one of the locking tabs can be inserted under at least one of therounding tabs to lock the neck so that this is a preferred but optionalfeature of the invention.

Closure scores 17, 25, 26, 29, 30, 78 and 79' generally parallel theirrespective portions of the bottom edge of the blank so that they can befolded over to form closure tabs 94 to close the bottom in a manner yetto be described.

In the event that a self-handle is desired, a construction can be formedsuch as that shown in FIG. 1, where slits 86, 87 are formed to definethe outer portion of a handle and in which central slits S8, 89 areformed to define a handle cavity. This provides two handle flaps 9t), 91which can be raised out of the flat surface to provide a self-handle. Itis evident that instead of a self-handle, a separate handle piece couldbe attached such as by cementing or stapling, if preferred.

Blank 119 of FIG. 7 includes a neck edge 111, a bottom edge 112, and twoside edges 113, 1-14.

A bottom surface is defined by a bottom front score 116, a centralsegment 117' of the bottom edge, and a pair of bottom side scores 118,119. The bottom surface is generally trapezoidal, score 116 beingparallel to central segment i117. Scores 118 and 119 converge towardeach other as they approach the bottom front score.

The device is symmetrical around a center line 120. Elements recited forthe surfaces on one side thereof are the same as those on the other.

Contiguous to the bottom side scores are two pairs of body flutesurfaces 121, 122, 123 and 124. Body flute surfaces 121 and 123 arecontiguous to and partially bounded by bottom side scores 118, 119,respectively.

Body flute surfaces 121 and 123' are further bounded by segments 125 and126 of the bottom edge, and by body flute scores 127, 128, respectively.Body flute surfaces 122 and 124 are bounded by segments 129 and :130 ofthe bottom edge, and by body side scores 13 1, 132, respectively, andalso by body flute scores 127 and 128, respectively. Body flute surfaces121-124, inclusive, are substantially isosceles triangles, and are allnearly conguent.

Bottom front score 1 16, bottom side score 118, body flute score 127,and body side score 131 meet at a body flute base junction 1333. Scores116, 119, 128 and 13-2 meet at a body flute base junction 134. Thesejunctions are not precisely points in the sense that all lines meet at asingle point. Instead, they are indicated by dotted lines as regions toindicate a convergence therein. These regions do act as junctions, buteach includes several spaced-apart points of intersections, to minimizethe amount of folding taking place within a limited area. It isdesirable, but not essential, to limit the number of folds adjacent to asingle point. However, as to function of the surfaces which converge atthese junctions, their result is still that the junctions functionsubstantially as points in determining the shape and configuration ofadjacent areas.

Two side surfaces 137, 138 are contiguous to body flute surfaces 122 and124. Surfaces 137 and 138 are bounded by side scores .131, 132, body topscores 139, 149 and side transition scores 141, 142, respectively. Theside transition scores are essentially continuations of the bottom frontscore and emanate from the respective body flute base junctions 133' and134 to front junctions 143, 144, respectively. The body top scores interconnect respective front junctions with side junctions 145, 14a at whichmeet body side score 131 and body top score 134 at junction 145, andbody side score 132 and body top score 149 at junction 146. In addition,closure score 129 intersects other scores at junction 145.

A neck bottom surface 147 is contiguous to bottom surface 115 and isbounded at one side by bottom front score 116. Two neck side scores 148,149 converge as they extend forwardly away from the bottom surface anddiverge on the opposite side of tab score 185, beyond which theyintersect the neck edge of the blank. The neck side scores are not,strictly speaking, straight lines because of this deviation, but theirsegments are.

Two first neck flute surfaces #154, are formed contiguous to the neckbottom surface and are bounded partly by neck side scores 148 and 149,respectively. They are also bounded by neck flute scores 156, 157 and bythe tab score. The neck flute scores intersect the region defined asbody flute base junctions 133 and 134,

although they are somewhat spaced apart from the neck side scores toavoid excessive folding stress concentrations at a single point ashereinabove described.

Second neck flute surfaces 158, 159 are formed contiguous to respectivefirst neck flute surfaces and are bounded by one side by neck flutescores 156 and 157. They are additionally bounded by neck top scores169, 161, by side transition scores 141, 14-2, respectively, and also bytab score 185. They are essentially quadrilateral surfaces. Theyintersect top scores 139 and 144} at front junctions 143 and 144.

Neck top surfaces 176, 171 lie contiguous to second neck flute surfaces153, 159, respectively. They are bounded at one side by neck top scores16%) and 16 1, respectively. Top medial scores 172, 173 extend fromfront junctions 143, 144, respectively, toward the side edges. Theirprecise location will be discussed more fully below.

Body top surfaces 176, 177 are contiguous to side surfaces 137 and 138,respectively, and are partially bounded by them.

The upper edge, preferably but not necessarily, has a rounding tab 180.Locking tab 183 is contiguous to neck top surface 170. The rounding tabfolds down to provide a rounded edge which will not cut, and the lockingtab can be inserted under it to lock the neck into an integral shape.

A snap score 199 intersects top medial score 173, and preferably is itsperpendicular bisector.

A self-handle and top reinforcement is provided to give a convenientmeans for carrying the device, and also for keeping it in its erectedconfiguration. A first handle hinge score 191 is contiguous to neck andbody top surfaces 170 and 176. A second handle hinge score 192 is spacedfrom score 191, and is parallel to it. Halfway between the two is handlecenter score 193. First and second handle surfaces 194 and 195 areformed between scores 192 and 193, and between scores 191 and 193,respectively. Finger holes 196 are cut in the handle surfaces. Thehandle surfaces are preferably mirror images so that they can be hingedtogether around score 193. Top medial score 172 courses across surfaces1% and 195, and is preferably normal to score 193.

Top reinforcement surface 197 is contiguous to surface 194. Top medialscore 172 courses across it.

The folding up of the device of FIGS. 1-7 will now be described. FIG. 1shows the ultimate setup configuration, and it will be observed that thebottom surface is to be flat on the bottom with the body flute surfacesfolded together and overlaying the bottom surface. The blank can befolded in either direction from flat, so that the numerals refer toscores and surfaces on both sides of the blank. The side surfaces risefrom the bottom, which bottom includes the folded-in body flutesurfaces. The body top surfaces are folded over, one atop the other. Theclosure tabs are folded up and forward and cemented together to make agood fluid seal for the bottom edge. Altern-ately, they can be left flatand sealed fiat together. Also, cement may be placed between theoverlapping body surfaces to make a fluid seal there.

The neck bottom surface is folded up to make an angle with the bottom.When the body top surfaces were folded over, the neck top surfaces werealso folded over. At this time, the neck flute scores will have beenpushed inward into the neck so as to form the neck flutes and the necktransition surfaces and bottom transition surfaces will have cockedangularly relative to each other to compensate for the angulardifference between their adjacent surfaces.

Ordinarily a certain amount of fluid sealing will be accomplishedbetween the neck top surfaces, such as by cementing, to stop leakage.This may be accomplished in the same operation as when the body topsurfaces were glued together. Rounding tabs, if used, will have beenfolded over, and the locking tabs inserted before the cementingoperation, and this will be found convenient in holding the devicetemporarily assembled during that time.

FIG. 3 shows an interim step in the folding up operation, the body topsurfaces being normal to the plane of PEG. 3 in that illustration, sothat only their edges show. At this time, the bottom flute scores 27 and28 will be pushed inward and folded so that the body flute surfaces 21,22, 23, 24 fold flat to overlay the bottom surface. The side surfacesstill extend generally horizontal and sideward while, when a neck medialscore is used as illustrated, that portion of the neck bottom surfacewhich lies between it and the bottom front score, will move down andoverlay a portion of the bottom surface. The neck flute scores are alsopushed inward.

The step following that shown in FIG. 3 is to round over and lock thetab scores and rounding tabs. Also the closure tabs are folded upward atthe bottom edge. Then a sealing operation, such as cementing, is carriedout by sealing between the neck top surfaces, the bottom top surfaces,and the closure tabs. The device is then fully set up.

Should only a top medial score be provided, and not a neck medial score,then the neck will be folded over onto the top of the body for thisassembly technique. However, this is somewhat more difficult, so thatordinarily both top and neck medial scores will be provided, therebyenabling the device to be stored flat either in the configuration shownin FIG. 5 with the neck extended, or, as shown in FIG. 6, with the neckreversed and overlaying the body. However, in the event that it is notdesired to provide means for the device to be stored in both of theflattened configurations, then either the top medial scores or the neckmedial score may be eliminated.

It can also be seen in FIG. 3 how the neck transition surfaces and thebottom transition surfaces have folded atop each other to compensate forthe difference in direction of their adjoining surfaces.

The small quadrilateral regions which lie between the neck side scores,neck flute scores, side medial scores and the side transition scoresperform a transition function, but it is one of relieving stressconcentration by separating scores 49 and 57, and scores 48 and 56.

The handle portion is utilized by lifting the handle flaps up off bodytop surfaces and pushing inwardly between them the flap formed by thecentral slits.

If a self-handle is not used, then one of the body top surfaces need beonly a margin for cementing purposes. However, assembly techniques aresimplified if two full body top surfaces are used, because then theedges can readily be matched. Alternatively, somewhat more than one-halfof each of the body top surfaces and neck top surfaces could beprovided, and a seam formed up the middle of the set up top and body.However, this, too, is a bit more difficult to assemble, and in bothcases, it may be necessary to either sacrifice the locking tabs, orprovide a more complicated arrangement for them.

Also, it is possible to fold the body flute surfaces underneath bottomsurface 15 instead of atop it, and still have the same structure.Therefore the term overlay as used in reference to the arrangement ofthe body flute surfaces relates to either folding the body flutesurfaces so they are inside the urinal and adjacent to the top face ofthe bottom surface, or outside the urinal adjacent to the bottom face ofthe bottom surface.

Instead of turning closure tabs 94 over and sealing them, they may besealed flat, and by eliminating or shortening the closure tabs on theflute surfaces, a smooth sealing joint can be made directly between theclosure tabs on the bottom surface and the body top surfaces.Ordinarily, best assembly technique will suggest that there be at leastsome closure tab left on the body flute surfaces so that they can becemented in place. The closure tabs on the bottom surface and on thebody top surfaces would then preferably be a bit longer so they couldfeather at the edge and make a direct seal without being held apart bythe body flute surfaces.

It will be observed that the top medial score and the neck medial scorelie substantially parallel to each other when the device is flattenedand the location of the junctions are defined as being along the line offold which results when the neck is flattened and the body is flattenedagainst the bottom.

The folding up of the blank shown in FIG. 7 will now be described withreference to FIGS. 7-9. The blank is laid flat, with botom surface 115facing upwardly. The blank is folded at bottom side scores 118 and 119',and at neck side scores 143 and 1 th. These motions bring body flutesurfaces 121 and 123 over the bottom surface, and first neck flutesurfaces ld i and 155 over the \neck bottom surface. Bending will occurat bottom front score 116 to permit these successive movements.

Next, the blank is folded at body flute scores 127 and 123, and at neckflute scores 156 and 157, so that body flute surfaces 122 and 124, andsecond neck flute surfaces 153 and 159 are folded over the respectivebody and neck flute surfaces to which they are adjacent. This forms apair of flutes at both sides of the structure.

The blank is next folded at body side scores 131 and 132, at top scores139 and 141 and at neck top scores 169 and 161. By this action, body topsurface 177 and neck top surface 171 are brought over bottom surface 115and neck bottom surface 147, and top surface 176 and neck top surface170 are brought over the reverse sides of surfaces 177 and 171, to whichthey may be cemented. This movement causes side surfaces 137 and 138 torise and form the major portion of the side of the structure above thebottom. Neck flute surfaces 158 and 159 form a continuation of them inthe neck region.

The bottom edge segments overlay each other neatly, and may be cementedtogether. Closure tab 2% is folded underneath the bottom, along closurescore Zill and cemented there to form a positive fluid seal around theedge segments. The rear edge of the folded structure is thus linear, andreliably, conveniently, and positively sealed.

A handle is formed by folding the blank at scores 191, 192 and 193, tobring handle surfaces 194 and 195 together. It is preferable to cementthese surfaces together, in order to provide the most effectivesnap-locking arrangement, but this is not essential. Top reinforcementsurface 197 is then cemented to the reverse side of neck top surface171.

At any convenient time during the above assembly operations, roundingtab 18% is folded over and locking tab 183 is inserted inside its foldto give reinforcement and a smooth edge to the open end of the neck.

The device may be collapsed by folding in the flutes and pressing thetop toward the bottom. It can readily be folded to substantially thecondition shown in FIG. 6, but not to that of FIG. 5. When it iscollapsed, the handle is folded along the top medial score so that itcan both lie flat against the top, but can fold with the rest of the topmedial score. The snap score permits the top to form a slight dome atthe mid-point of the handle, which tends to be a stable condition whenthe handle is erect. In fact, it is not possible to collapse thestructure with the handle erect, and, with the snap structure, thehandle will not fold down unless forcibly pushed. When it is foldedover, and the center of the top pressed down, the snap action iseffective in further collapsing the device and holding it collapsed.This is a second stable condition.

The scores are generally straight lines and the various surfaces are, ingeneral, triangular, quadrilateral, or the like, and lie flat. Complexcurved lines and boundary surfaces and complex three-dimensionalsurfaces when set up are in general avoided, which gives better foldingcharacteristics and, in operation, a more stable unit. Furthermore, thedevice is thoroughly and reliably sealed along straight edges and ismade of a single piece, thereby 8 obviating the sealing problems whichhave existed in prior art devices.

The preferred embodiment has the additional advantage of fewer scores,plus a pronounced snap-acting feature. This latter is inherently presentin the device of FIGS. 1-6, but not to the extent of that shown in FIGS.79.

This invention is not to be limited to the embodiments shown in thedrawings and described in the description which are given by way ofexample and not of limitation, but only in accordance with the scope ofthe appended claims.
